What are the bid evaluation methods?

The bid evaluation methods are:

1. Comprehensive bid evaluation method: Convert the various qualifications, technology, business and service terms of the bidder involved into a certain price Score value, total score is 100 points. During the bid evaluation, each indicator of the bidder will be reviewed and checked for compliance and a score will be given. Finally, the bid will be summarized and compared, and the bidder with the highest score will be selected as the winning bidder.

2. Method for winning the bid with the lowest price after evaluation: Convert the indicator requirements involving the bidder's various technical, business and service contents into prices according to unified standards, compare them, and obtain the "evaluated bid price" The lowest bidder’s method shall be adopted.

3. Cost-effective bid evaluation method: It is a special comprehensive bid evaluation method. After reviewing the bid documents according to the requirements, other scoring factors other than the price factor are calculated for each valid bidder. The summary score is divided by the bidder's bid price, and the bidder with the highest quotient (total bid evaluation score) is the bid-winning candidate supplier or the bid-winning supplier.

4. Lowest price winning bid method: suitable for bidding of large quantities of simple goods. Model specifications and quality standards are relatively simple and clear. When bidding is held, the bidder with the lowest bid will win the bid.

5. The method of determining the winning bid based on the base bid: a commonly used bidding method in the early years. The tenderer asks someone to carefully calculate the reasonable total cost of the project, which is used as the "base bid" and is kept strictly confidential; after the bid is opened and the bid is sung, the base bid is announced, and the bidder closest to the base bid wins the bid. This method is rarely used now.

6. Double-envelope bid evaluation method: a method used in project bidding. The bidder submits two envelopes of technical and commercial quotations at the same time; the technical envelope is opened first for analysis and comparison. For those who meet the requirements, the envelope of the quotation will be opened, and the lowest bidder will win the bid.

7. Two-stage bidding evaluation method: adopted for large and complex complete sets of equipment or projects. It is used when the buyer (tenderer) is not familiar with the technology and has no idea. In the first step, bids for "technical solutions" (not involving price) will be invited; for those who meet the requirements, bids with commercial quotations will be made in the second step.
